' AEROPLANE'.

To all whom it may concern:

Be it known that I, Jon SoHRAM, a citizen of the United States, residing at Lawton, in the county of Comanche and State of Oklahoma, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specification.

This invention relates to improvements in aeroplanes and particularly to types in which planes extend laterally from the fuselage.

The principal object of the invention is to provide means by which the planes may be moved on their pivotal supports thus varying the angle between them and the longitudinal axis of the fuselage.

Another purpose is to connect the planes in such a manner that they are moved simultaneously.

A further object is to provide means for manually operating the planes by an operator in the cock-pit of the fuselage.

These several objects are attained by the novel construction, combination and arrangement of parts hereafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side view of a conventional type of flying machine embodying the invention.

Figure 2 is a front elevational View of the same. a

Figure 3 is a fragmentary side view similar to Figure 1, but showing the planes at a different inclination relative to the fuselage.

In the drawing, the numeral 5 designates generally the fuselage body in which is contained the motor, fuel and other impedimenta, the body having a cock-pit 6 for the operator and being provided with a pair of spaced landing wheels 7 together with a tailing support 8 at the rear.

At the front of the fuselage extends a motor driven shaft 9 having a propeller 10, and at the rear are vertical and horizontal rudders 11 and 12 respectively, actuated by rods 13 and 1 1 entering the fuselage to be operated by the driver in the cock-pit 6.

As shown in the drawing a bracket 15 is fixed on the upper side of the fuselage, at some distance in front of the cock-pit, this bracket being forked at its outer end and provided with pivots 16 by which are engaged lugs 17 supporting the upper plane 18.

The lower plane 20 is made in two sections, from the inner ends of which extend lugs 21 attached by pivots 22 to the sides of the fuselage near its bottom, directly below the pivots 16.

These planes are connected near their forward ends by bars 23 pivoted respectively to the lower surface of the upper plane and the upper surface of the lower plane, other bars 24 being similarly connected to the plane in rearward register with the bars 23.

Still another pair of connecting bars 25 are pivotally connected between the planes, adjacent the fuselage, rearward of the pivots 16 and 22 and extending out from the sides of these bars are pins 26 engaging in slots 27 formed in the horizontal member 28 of a bell-crank lever, pivoted on pins 29 set in the sides of the fuselage.

The vertical members 30 of these bellcrank levers terminate in handles 31 arranged convenient of access to the operator.

From the foregoing it will be seen that when the operator wishes to ascend, the handles 31 are pulled towards the rear, this action causing the bell-cranks to change the angularity of the planes, lowering the rear edge so as to effect such raising of the aeroplane.

Conversely, moving the handles forwardly, away from the operator, will cause the planes to dip, depressing the apparatus.

Having thus described my invention and set forth the manner of its construction and use, what I claim as new and desire to secure by Letters Patent, is

In an aeroplane, the combination with the fuselage, of a bracket extending above said fuselage, an upper plane pivoted to said bracket, a lower sectional plane, pivotal connections between the adjacent ends of the sections and body of the fuselage, connections pivoted to the adjacent surfaces of said planes, bars pivoted between said planes adjacent said fuselage, said bars having extending pins, bell-crank levers pivoted on said fuselage, one of the elements of each bell-crank lever engaging said pins, and handles formed on the other of said bellcrank elements.

In witness whereof I have afiixed my signature.

JOE SCHRAM.
